How to create an array with 2^n using this method?

In my homework, I'm asked to create an array of 8,16,32,...,2048 using the way :

N=[8 16 32 ??? 2048]

what could be the ??? here? Any operator? Not familiar with matlab...

I believe it is just describing the sequence.

N=2.^(3:11);

In general, please help people to do their homework, rather than doing it for them.
